Abstract

An electronic aerosol provision system includes a vaporizer for generating an aerosol using electrical power; a battery for supplying electrical power to the vaporizer and to other components of the electronic aerosol provision system; a flat, flexible cable having a laminated structure and incorporating multiple conductor lines for transmitting electrical power and/or signals; and a temperature sensor incorporated into the flat, flexible cable and located adjacent the battery for sensing the temperature of the battery. The electronic aerosol provision system is configured to detect an error condition if the sensed temperature of the battery goes outside a specified operating range; and in response to such detection, to reduce or cease the supply of electrical power from the battery.

First claim

The invention claimed is:

1. An electronic aerosol provision system comprising:
a vaporizer for generating an aerosol using electrical power;
a battery for supplying the electrical power to the vaporizer and to other components of the electronic aerosol provision system;
a flat, flexible cable having a laminated structure and incorporating multiple conductor lines for transmitting at least one of electrical power or signals; and
a temperature sensor incorporated into the flat, flexible cable and located adjacent the battery for sensing a temperature of the battery;
wherein the electronic aerosol provision system is configured to:
detect an error condition if the sensed temperature of the battery goes outside a specified operating range, and
in response to such detection, reduce or cease the supply of electrical power from the battery.

2. The electronic aerosol provision system of claim 1 , wherein the flat, flexible cable includes at least a first insulating layer and a second insulating layer, and wherein the multiple conductor lines and the temperature sensor are sandwiched between the first insulating layer and the second insulating layer.

3. The electronic aerosol provision system of claim 1 , further comprising a control facility, and wherein the flat, flexible cable includes at least one conductor line for communicating signals between the control facility and the temperature sensor.

4. The electronic aerosol provision system of claim 3 , wherein the temperature sensor is configured to:
notify the control facility of the sensed temperature over the at least one conductor line for communicating signals between the control facility and the temperature sensor;
and wherein the control facility is configured to detect an error condition if the sensed temperature of the battery goes outside the specified operating range.

5. The electronic aerosol provision system of claim 3 , wherein the temperature sensor is configured to:
detect an error condition if the sensed temperature of the battery goes outside the specified operating range; and
notify the control facility that the error condition has been detected over the at least one conductor line for communicating signals between the control facility and the temperature sensor.

6. The electronic aerosol provision system of claim 3 , wherein the control facility is configured to reduce or cease the supply of electrical power from the battery in response to the detection of the error condition.

7. The electronic aerosol provision system of claim 3 , wherein the control facility is configured to transmit a control command to the temperature sensor over the at least one conductor line for communicating signals between the control facility and the temperature sensor.

8. The electronic aerosol provision system of claim 3 , wherein the conductor lines of the flat, flexible cable are used for supplying electrical power from the battery to the control facility.

9. The electronic aerosol provision system of claim 3 , wherein the conductor lines of the flat, flexible cable are used for supplying electrical power to the temperature sensor from at least one of the battery or from the control facility.

10. The electronic aerosol provision system of claim 1 , wherein the temperature sensor is a resistance temperature detector.

11. The electronic aerosol provision system of claim 1 , wherein one end of the flat, flexible cable is connected to at least one terminal of the battery.

12. The electronic aerosol provision system of claim 1 , wherein the conductor lines of the flat, flexible cable are used for supplying electrical power from the battery to the vaporizer.

13. The electronic aerosol provision system of claim 1 , wherein the battery has a longitudinal axis and the flat, flexible cable extends in a direction parallel to the longitudinal axis.

14. The electronic aerosol provision system of claim 1 , wherein the battery has an external surface and the flat, flexible cable is approximately tangential to the external surface of the battery.

15. The electronic aerosol provision system of claim 1 , wherein the battery is re-chargeable, and wherein, in response to a detected error condition that the sensed temperature of the battery has gone outside the specified operating range, the electronic aerosol provision system is configured to reduce or cease a supply of electrical power to the battery for re-charging the battery.

16. The electronic aerosol provision system of claim 1 , further comprising at least one of an audio user interface or a visual user interface for notifying a user of a detected error condition.

17. The electronic aerosol provision system of claim 1 , wherein the temperature sensor directly contacts the battery.

18. The electronic aerosol provision system of claim 1 , wherein the temperature sensor provides a physical parameter which is temperature-dependent.

19. A control unit for use with an electronic aerosol provision system comprising a vaporizer for generating an aerosol using electrical power, the control unit comprising:
a battery for supplying electrical power to the vaporizer and to other components of the electronic aerosol provision system;
a flat, flexible cable having a laminated structure and incorporating multiple conductor lines for transmitting at least one of electrical power or signals; and
a temperature sensor incorporated into the flat, flexible cable and located adjacent the battery for sensing a temperature of the battery;
wherein the control unit is configured to:
detect an error condition if the sensed temperature of the battery goes outside a specified operating range, and
in response to such detection, reduce or cease the supply of electrical power from the battery.

20. A method of operating an electronic aerosol provision system comprising a vaporizer for generating an aerosol using electrical power, the method comprising:
supplying electrical power from a battery to the vaporizer and to other components of the electronic aerosol provision system;
sensing a temperature of the battery using a temperature sensor incorporated into a flat, flexible cable and located adjacent the battery, wherein the flat, flexible cable has a laminated structure and incorporates multiple conductor lines for transmitting at least one of electrical power or signals;
